Adenium Desert Rose

Adenium Caudex Rot is a severe fungal or bacterial infection that attacks the water-storing swollen trunk (caudex) of the Desert Rose plant. Driven primarily by waterlogging and fungal pathogens like Fusarium or Phytophthora, this condition rapidly breaks down the internal plant tissue, converting a solid trunk into a soft, mushy mess. Beginners often notice the issue when the stem yields under gentle pressure or when healthy leaves suddenly turn yellow and drop off en masse. Left untreated, the decay travels upward into the branches and downward into the feeder roots, leading to the total collapse of the plant in a matter of days. In Indian homes, this condition spikes during the heavy monsoon rains and cold winter periods. High ambient humidity combined with compact, clay-heavy garden soil or pots without adequate drainage holes traps moisture around the base, creating ideal conditions for stem rot.
